Acceleration
| Question | Answer |
|---|---|
| What is Acceleration? | The rate at which velocity changes over a period of time. |
| What are the 3 ways an object can accelerate? | Speeding up, Slowing down, Changing Direction |
| What is the formula for calculating acceleration? | a = vf -vi/t |
| What is vf? | final velocity |
| What is vi? | initial velocity |
| What is another word for initial? | starting |
| A person is running at a rate of 8m/s, then speeds up to a rate of 14m/s. What is their initial velocity? | 8m/s |
| How is a satellite orbiting Earth at a constant speed accelerating? | Because it is moving in a circle it is constantly changing direction, thus it is accelerating |
| What is an object doing if its acceleration is -5m/s/s | the negative sign tells us it is slowing down |
| A person on a bike is moving at a speed of 6 mi/hr when they see a bunch of people ahead on the sidewalk, so over a period of 5 seconds, they slow down to a speed of 2 mi/hr. What is their final velocity? | 2mi/hr |
| What is the acceleration of a skateboarder moving at a constant speed of 3.5 m/s in a straight line? | 0 m/s/s |
| How can a steering wheel in a car cause a change in velocity | Since a change in direction is a change in velocity, a turn of the wheel will cause a change in velocity. |
